Diesel-powered "car" edges on half the speed of sound

JCB, a UK firm which specializes in construction equipment (read: making tractors) appears to have become bored with life in the slow lane. At least that's what the company's sponsorship of the JCB DieselMax seems to suggest, as the team piloting the DieselMax just recently broke the diesel land speed record at 350mph (yeah, but does it have GPS?). The feat, which took place at the local Salt Lake City street racing venue on the Bonneville Salt Flats, puts the previous record of 237mph to shame, although it's worth noting that the new record is still awaiting ratification by the Fédération Internationale de l'Automobile. Unbelievably, the team isn't finished yet, with one crew member excitedly exclaiming that they "still haven't used sixth gear!" We also heard reports from an inside source that during the run the team decided not to turn up the volume to 11, either.
